AD 2016-10-03

This airworthiness directive (AD) becomes effective May 31, 2016.

None.

This AD applies to Viking Air Limited Model DHC-3 airplanes, all serial numbers, that are:

(1) Modified with the Baron Short Take Off and Landing (STOL) kit (Supplemental Type Certificate SA94-114 or SA 00287NY); and

(2) certificated in any category.

Air Transport Association of America (ATA) Code 8: Leveling and Weighing.

This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as an accident report that indicated that the center of gravity was too far aft and contributed to a stall during takeoff. We are issuing this AD to correct the center of gravity and prevent such a stall during takeoff and loss of control during other phases of flight.

Unless already done, within 30 days after May 31, 2016 (the effective date of this AD), remove whichever previous revision of the Otter Baron short take-off and landing (STOL) kit installation flight manual supplement (FMS) that is currently being used and incorporate Stolairus Aviation Inc. Flight Manual Supplement #4 for de Havilland DHC-3 Otter with the Baron STOL Kit Installation, Revision 3, dated May 22, 2015. This action may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a)(1)-(4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Aziz Ahmed, Aerospace Engineer, FAA, New York Aircraft Certification Office (ACO), 1600 Stewart Avenue, Suite 410, Westbury, New York 11590; telephone: (516) 287-7329; fax: (516) 794-5531; email: aziz.ahmed@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.
